Bypassing interlock system

I hope I'm in the right spot, but we cut the wires on our bus and now it won't start. It's a 1995 Bluebird with a gas engine. We've been trying to re wire it at the electrical panel and cant seem to figure it out. I attached a picture of the wires and wiring diagram. Thank you

This is why it pays to research. Three things people should NEVER mess with on their bus, and that's one of them.

Where (like, where physically inside the bus) did you cut the wires?

Looks like solenoid #1 and #2 are gone. Definitely need more info on the bus and what wires you cut.

We cut them at each emergency exit and the doors. Just the wires that made them impossible to remove

Check your fuses near the cockpit area. I think you blew one for the ignition. Is your bus completely dead when turning the key?
If so, it should be 10 amp fuse. Pull it out and test with a continuity tester along with visual.
The pink and orange wires I think are energized so make sure to tape them off where you cut them.

Well, hopefully all you need to do to get your bus started at least is to ground the powered wire leading to the barrel lock on your side exit door. The interlock is basically a single circuit that needs to be continuous for the bus to start. When either of the barrel locks on the emergency doors is thrown (meaning the door cannot be opened), this breaks the circuit and the bus can't be started.

If you locate the powered wire leading to the barrel lock on the side, you can strip the end and connect it to the bus body with a sheet metal screw. This will complete the circuit and allow your bus to start (the barrel lock will also have a second wire for ground - if you ground that on instead of the powered wire, the bus still won't start). You could also just splice the two wires (powered and ground) together to complete the circuit.

Note: you want to do this with the wire leading to the side door rather than the back door because the side door is the first one in the circuit (with the wires cut the back door barrel lock is not receiving any juice anyway, so grounding the powered wire won't do anything). You said you also cut wires on your doors (plural), and I'm not sure where they are in this circuit (or if they're even part of the starter interlock at all - I don't think they are).

I bypassed my interlock in this way. I want to keep the circuit active because when I complete my conversion, I'm going to wire it up to cabinet doors and stuff that I want to make sure I remember to close whenever I drive (like a cat door I'm going to put on my exit door).

I chose to bypass the entire lock out system on my '99. If you read post #13 in my build thread, I go over what I did and where the relay to bypass is located. I don't know if it is exactly the same on a '95, but this should be close enough info to get you pointed in the right direction.

unless theres a reason to keep it.. ie your kids like to open doors going down the road.. then completely disanbling the onterlocks right at the electrical panel seems like the way to go.. no worries of cutting a wire in the futire or something gets cut by accdeint and you get stranded
